ASTM A213, marka lagu daro shuruudaha sifooyinka adkaanta iyo adkaanta, tijaabooyinka soo socda ayaa sidoo kale loo baahan yahay: Tijaabada Fidsan iyo Tijaabada Laabista.
ASTM A335 P22(ASME SA335 P22) waa tuubo bir ah oo aan lahayn chromium-molybdenum ah oo adeeg heerkul sare leh oo aan kala go 'lahayn, oo si ballaaran loogu isticmaalo warshadahakuleyliyeyaasha, kuleyliyeyaasha aadka u sarreeya, iyo kulaylkabeddelayaasha.
Waxay ka kooban tahay 1.90%ilaa 2.60% chromium iyo 0.87% ilaa 1.13% molybdenum, waxay leedahay iska caabin kulayl oo aad u fiican, waxayna sidoo kale ku habboon tahay foorarsiga, kala-goynta, ama hawlgallada sameynta ee la midka ah.
Lambarka UNS: K21590.
ASTM A335 waa qeexidda caadiga ah ee tuubooyinka birta-ferritic ee aan kala go 'lahayn ee loogu talagalay adeegga heerkulka sare. Waxaa si weyn loogu isticmaalaa kuleyliyeyaasha, kuleyliyeyaasha sare, beddelayaasha kulaylka, iyo codsiyada kale ee ka shaqeeya xaaladaha heerkulka sare iyo cadaadiska sare. Marka laga soo tago Darajada P22, darajooyinka kale ee daawaha caadiga ah waxaa ka mid ahP5 (UNS K41545), P9 (UNS K90941), P11 (UNS K11597), iyoP91 (UNS P90901).
Soo-saaraha iyo Xaaladda
Tuubooyinka birta ah ee ASTM A335 P22 waa in lagu sameeyaa habka aan kala go 'lahayn waana in lagu sameeyaa mid kulul ama mid qabow lagu soo jiido iyadoo la adeegsanayo habka dhammaystirka.
Tuubooyinka birta ah ee aan xuduud lahaynwaa tuubooyin aan lahayn alxan, kuwaas oo siiya tuubooyinka birta ah ee P22 xasillooni iyo isku hallayn sare jawi heerkul sare iyo cadaadis sare leh.
Daaweynta Kulaylka
Tuubooyinka birta ah ee P22 waa in dib loo kululeeyaa oo lagu daaweeyaa kuleyl ahaan iyadoo la isticmaalayo annealing buuxa, annealing isothermal, ama caadiyaynta iyo tempering-ka.

Chromium (Cr) iyo molybdenum (Mo) waa walxo muhiim u ah isku-darka birta P22, iyagoo hagaajinaya xoogga heerkulka sare, iska caabbinta oksaydhka, iyo cimri dhererka. Halabuurka kiimikada gaarka ah waxaa lagu muujiyay hoos:
| Fasal | Halabuurka, % | ||||||
| C | Mn | P | S | Si | Cr | Mo | |
| P22 | 0.05 ~ 0.15 | 0.30 ~ 0.60 | ugu badnaan 0.025 | ugu badnaan 0.025 | 0.50 ugu badnaan | 1.90 ~ 2.60 | 0.87 ~ 1.13 |
Tijaabooyinka hantida farsamada ee P22 waa in lagu sameeyaa iyadoo la raacayo shuruudaha khuseeya ee ASTM A999.

Dulqaadka Dhexroorka
Tuubada ay dalbatay NPS [DN] ama dhexroorka dibadda, kala duwanaanshaha dhexroorka dibadda waa inaysan dhaafin shuruudaha ku cad jadwalka hoose:
| NPS [DN] Naqshadeeye | Kala Duwanaanta La Ogol Yahay | |
| gudaha. | mm | |
| 1/8 ilaa 1 1/2 [6 ilaa 40], inji. | ±1/64 [0.015] | ±0.40 |
